The M-7019Z is a 10-channel universal analog input module with an RS-485 interface that is specially designed for extremely accurate thermocouple measurement and features automatic cold-junction compensation for each channel to ensure temperature output consistency and stable temperature output in the field. The innovative design of the enhanced model ensures that thermocouple measurement is more accurate than with the earlier design.

Besides the thermocouple inputs, The M-7019Z also supports voltage and current inputs. The voltage input range can be from ±15 mV to ±10 V, and the current input range can be either 4 ~ 20 mA, 0 ~ 20 mA, or ± 20 mA. Up to 10 analog inputs of different types can be connected to a single module.The module also provides up to 240 Vrms overvoltage protection and features per-channel open wire detection for the thermocouple and +4 ~ +20 mA input types.
